God, this is such a fascinating game, man. Not unlike other Ferociter works, it first drew me in with its mysterious surreal atmosphere, and got me hooked as a strange and unique adventure unfolded.
Top-down adventure games have become common since the era of RPG maker, but many of them fail to escape the formula of just "put item on thing" or some simple puzzles based on memorizing a clue, but this game, with its sailing and fog mechanics, has some really interesting gameplay ideas to it. The sea in which we navigate is basically a strange non-linear world that we can't really navigate as if it was a normal sea, instead requiring you to do some cryptic shenanigans to get to different locations.
What really sells the game, though, is definitely the variety in strange, curious, surreal puzzles. They go way beyond just "follow the instructions on screen," requiring a decent amount of lateral thinking and logic, and each puzzle is completely different from the last.
There are a few problems, though. For instance, when trying to go down the streams, you can sometime get trapped at the very top, forcing you to cover the lantern to restart. There is also no tooltip for lantern covering, I kinda discovered it by accident. Also, with us having to go back and forth between islands, it would be cool if there was a way to do so without having to repeat the overworld puzzle every time. One last thing, it feels like this one doesn't really have much a story conclusion, despite the puzzles being cool.
All in all, this is the kind of stuff I point to when someone tells me games can't be art. This is basically one small, playable combination of artistic ideas. Really cool game, with a few small problems.
